The Genie 55921GT is a genuine OEM Socket Head Cap Screw, 3/8-24 x 1.25 built for Genie GS scissor lifts, articulating boom lifts, and trailer-mounted booms, including the GS-4047, TZ-50, and Z-30/20 N.

Confirm part number 55921GT against your machine's parts manual to ensure it is the correct fastener for your application.
Key Features
- OEM Thread and Dimensional Conformity — Manufactured to the exact 3/8-24 thread pitch and 1.25-inch length specified by Genie, ensuring the fastener engages correctly without rework.
- Socket Head Cap Design — The recessed hex drive allows installation in tight or countersunk locations where a standard hex head fastener may not fit.
- Direct OEM Replacement — Sourced directly through Genie's genuine parts program, this screw matches the original component character for character.
- Broad Genie Fitment — Compatible with the GS-4047 scissor lift, TZ-50 trailer-mounted boom, and Z-30/20 N articulating boom, covering multiple Genie equipment families.
- Structural Integrity Where It Counts — A fastener of the wrong thread pitch or length can compromise the joint it secures; using the correct OEM screw maintains the clamping force the design demands.
A socket head cap screw is a high-strength threaded fastener with a cylindrical head and an internal hex (Allen) drive socket. On Genie aerial lifts and booms, these screws are used in assemblies where precise torque and a low-profile head are required — such as mounting brackets, pivot points, and structural covers. A screw with the wrong thread specification or length may strip, bottom out, or fail to clamp properly, leading to loosening under load. Replacing a worn or missing fastener with the correct part, part number 55921GT, restores the joint to its original holding strength.
